摘　　要：文中论述了采用EH4连续电导率剖面仪,在安徽铜陵冬瓜山铜矿区参加全国危机矿山找矿方法对比试验的应用效果。冬瓜山铜矿床具有矿体埋深大、规模大、人文干扰因素大的特点,EH4电磁测量资料经过各项处理,有效地压制了干扰影响,反映出矿区内地质构造特征、地层岩性分布和地下矿化体赋存部位与空间产状,达到了预期的探矿目的和对比试验效果。In this article, we describe the application result of EH4 continuous electric conductivity section instrument in Dongguashan cuppor mine area, Tongling, Anhui Province, in national comparison of exploration methods on crisis mine. Dongguashan cop- per orebodies are buried deeply, with large size and severe disturbance of human beings. After processing by kinds of methods, the noise was suppressed effectively and the EH4 data could reflect the characteristics of geologic structure, the distribution Of stratum lithology and the position and shape of mineralization bodies. And the anticipative prospecting aim and the effect of comparison test were achieved.
